SPECIFICATION forming part of Letters Patent No. 650,186, dated May 22,1900.

Application filed December 23, 1899. Serial No. 741,489. (No model.)

T0 @ZZ whom t may concern:

Be itknown that we, GEORGE D. MAXSON, of the town of Brookfield, in thecounty of Madison, and LYNN C. MAXsoN, of West Edmeston, in the countyof Ostego, State of New York, have invented certain new and usefulImprovements in Pliers; and we do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form part of thisspecification.

The object of our invention is to provide pliers which are simple inconstruction and of aconstruction which adapts them for effective use indrawing staples, nails, dac., as well as for use as'ordinary pliers.

In the drawings, Figure l shows a perspective view of our improvedpliers. Fig. 2 shows a plan oratop viewof the pliers. Fig. 3 shows aside or edge View. Fig. 4 shows the opposite side from that shown inFig. 3. Fig. 5 shows an end view.

Referring to the reference-figures in a more particular description, 1and 2 indicate the handles, which are integral with the jaws 3 and 4,respectively, and are pivoted together at 5. The working points of thejaws 3 and 4 are made narrow to allow them to be easily inserted in theloops of staples which the tool may be employed to draw. The insidefaces of the working parts of the jaws are made concave and come incontact with each other only at the points, as shown in Fig. 2. Thehandle and jaw 4 includes also a horn or projection 6, extendinglaterally from the jaws in the plane of the point of separation betweenthe working points or por tions of the jaws. .The working face of thehorn or projection 6 is an irregular curve, as shown. The points of thejaws are substantially in line with the face of the base portion of thehorn or projection 6, as appears by the dotted line vin Fig. 4, and thejaws areseparated from the base portion ofthe horn or projection by arecess or space 7,.providing a clearance-space for the lower prong of astaple when the loop is forced well back in the jaws and which makes theworking portions of the jaws have a separate and individual nature,permitting their use as ordinary pliers and enabling the points to beforced into wood or other material in getting under the heads of nailsand into the loops of staples which are driven deeply into the wood.

In the particular use for which these. pliers are adapted the points ofthe jaws, which are made narrow, as shown in Fig.r2, to enable them tograsp staples the loops of which are driven into uneven surfaces ordepressions, are inserted into the loop of the staple and the handlespressed together, which operation grips the points of the jaws into theloop of the staple, and by reason of the shape of the working faces ofthe j aws,as set forth, the loop of the staple is forced back into astronger portion of the jaws away from the points before the strain ofdrawing the staple is brought upon the jaws. If the loop of the stapleis driven close to the surface of the wood, the foregoing operation,will force the narrow points of the jaws into the wood, making therelative position of the jaws and staple the same as in thelast-mentioned case. After securing hold of the staple the handles ofthe pliers are then borne down, forming a lever the fulcrum of which isfirst at the upper or base portion of the horn, where a powerfulleverage is obtained. The staple in being drawn olfers the strongestresistance at the starting-point. VThe resistance constantlydecreasesuntil it is fully withdrawn from the wood. As the handles are borne downthe fulcrum constantly changes toward the lower portion of the horn orprojection 6, where a less powerful leverage is obtained. By thisconstruction there is provided a leverage the power of which constantlydecreases as the resistance offered by the staple decreases,

Ywhereby a substantially-uniform amount of power is utilized throughoutthe operation. As the fulcrum constantly changes farther from the stapleas it is being drawn, the staple is drawn more approximately in a directline than if the fulcrum were at one fixed point where the maximumleverage could be obtained. The staple is also drawn without being bent,so that it is in condition for subsequent use. The tool may be operatedsubstantially the same in drawing nails.

IOO

What we elaimias new, and desire to secure by LettersPatent, is-f` Thecombination in pliers of the jaws or parts 3 and 4 formed With narrowpoints and l including handles, respectively, pivoted'together, and.4the laterally-projecting` part 6. having an irregular-curvedbearngffaee, the j portion of which face nearest to theworkngl points ofthe jaws is in a plane with that of ing point of the jaw 4 wherebytherecess oi clearance-space 7 is provided,substantially as set forth.

In Witness whereof we have affixed our signatures, in presence of twowitnesses, this 8th .day of December, 1899.
